Abstract
Disclosed is an implantable cardiac electrode for use in defibrillation. The electrode has a metallic mesh electrode surface surrounded by an insulating material which is formed so as to increase the metallic surface area while providing a substantially uniform current density across the electrode surface. An additional electrode tip is included for use in the event that pacing is required; the pacer tip may have a detachable lead for removal after surgery. The electrode may be implanted without major surgery by means of a specialized insertion tool which cooperates with a pocket formed in the electrode. After implantation, the electrode may also be used as a pick-up in an electrocardiogram system.
